Install the new module

or in case you want the modules installed a specific place. For example: /lib/modules/`uname -r`/{misc,extra}

# cp pwc.ko <path to the folder of original pwc.ko module>

Update module dependency and map files

# depmod -a

Unload old pwc/pwcx modules

If you already had an old version of pwc/pwcx installed you need to unload them first. You can also just simply reboot the machine. If you are not sure run the commands anyway. They will not harm anything.

# rmmod pwcx
# rmmod pwc

Load the new module

Finally load the new pwc module. Note that there is no longer any binary pwcx module to worry about. It is all in the pwc module
